2-2. Temperature Characteristics of Release Voltage
The temperature change ^{Δ + VDET} of the release voltage is calculated by using the temperature
ΔTa
chnange ^{Δ − VDET} of the detection voltage as follows:
ΔTa
Δ + VDET ₌ +VDET _× Δ − VDET
ΔTa
− VDET ΔTa
The temperature change of the release voltage and the detection voltage have the same sign
consequently.
